Treatment of pediatric bilateral condylar fractures: A comprehensive analysis.

Pediatric bilateral condylar fractures (PBCF) is a rare clinical pathology, where the management is carried out with both conservative and surgical approaches. The purpose of this study was to analyze and compare these two treatment approaches and their associated long term complications in PBCF. An extensive literature review- through the search of online databases- was conducted to survey, collect, analyze and compare the reported outcomes of different treatment modalities for PBCF. The number of studies presenting PBCF case reports was 16, while the number of such retrospective studies included here was 19. Analyses of these studies revealed that the conservative treatment is preferred in PBCF patients younger than 12 years of age. Moreover, a composite approach where the open reduction and internal fixation (ORIF) is carried out for one side while the intermaxillary fixation (IMF) for the contralateral side is frequently reported for the management of PBCF cases; this approach appears effective in improving daily functioning of temporomandibular joint and reducing long term complications. Performing ORIF for one side while IMF for the contralateral side seems the most common treatment approach in PBCF. This study may help in rapid decision making for treatment selection of PBCF patients while minimizing the risk for late complications.

Efficacy & safety of iodopovidone pleurodesis: a systematic review & meta-analysis.

BACKGROUND & OBJECTIVES: Chemical pleurodesis is an accepted therapy for patients with recurrent pleural effusions and pneumothorax. Iodopovidone has been shown to be safe and effective for chemical pleurodesis in several studies. The aim of this systematic review was to update a previously reported meta-analysis on the efficacy and safety of iodopovidone pleurodesis. METHODS: Two databases MEDLINE and EMBASE were searched for a period (1952-2010), and studies that have reported success rates with iodopovidone pleurodesis were selected. The proportions with 95 per cent confidence interval (CI) were calculated to assess the outcomes in the individual studies and the results were pooled using a random effects model. RESULTS: Thirteen eligible studies with 499 patients were included in the mata-analysis. The success rates varied from 70 to 100 per cent in different studies with the pooled success rate being 88.7 per cent (95% CI, 84.1 to 92.1). The success rate was not affected by the method (tube thoracostomy vs. thoracoscopy, 89.6 vs. 94.2%) or the indication of pleurodesis (pleural effusion vs. pneumothorax, 89.2 vs. 94.9%). The only significant complication reported was chest pain of varying degree. Systemic hypotension was reported in six patients across the studies. There were no deaths associated with iodopovidone pleurodesis. Statistical heterogeneity and publication bias were found. INTERPRETATION & CONCLUSIONS: Iodopovidone may be considered a safe and effective agent for chemical pleurodesis in patients with pleural effusions and recurrent pneumothoraces.

Green synthesis and biomedicinal applications of silver and gold nanoparticles functionalized with methanolic extract of Mentha longifolia.

This study deals with facile and rapid synthesis of silver nanoparticles (AgNPs) and Gold nanoparticles (AuNPs) using Mentha longifolia leaves extracts (MLE). The synthesized AgNPs and AuNPs were characterized by UV-visible spectroscopy (UV-Vis), Fourier transformed infra-red spectroscopy (FT-IR), atomic force microscopy (AFM) and transmission electron microscopy (TEM) techniques. The phytochemical analysis showed the presence of bioactive secondary metabolites, which are involved in the synthesis of nanoparticles (NPs). The surface plasmon resonance (SPR) observed at 435 and 550 nm, confirmed the green synthesis of AgNPs and AuNPs, respectively. The TEM images showed poly dispersed and round oval shapes of Ag and Au NPs with an average particles size of 10.23 ± 2 nm and 13.45 ± 2 nm, respectively. TEM results are in close agreements with that of AFM analysis. The FT-IR spectroscopy revealed the presence of OH, -NH2 and C = O groups, which involved in the synthesis of NPs. The MLE and their AgNPs and AuNP exhibited good in vitro antibacterial and anti-oxidant activities. Moreover, MLE and NPs also showed in vivo analgesic activities in mice, and excellent sedative properties in open field test paradigm.

Sedative and muscle relaxant activities of diterpenoids from Phlomidoschema parviflorum

Abstract Phlomidoschema parviflorum (Benth.) Vved. (Basionym: Stachys parviflora Benth.) Lamiaceae, have significance medicinal importance as it is used in number of health disorders including diarrhea, fever, sore mouth and throat, internal bleeding, weaknesses of the liver and heart genital tumors, sclerosis of the spleen, inflammatory tumors and cancerous ulcers. The present contribution deals with the sedative and muscle relaxant like effects of diterpenoids trivially named stachysrosane and stachysrosane, isolated from the ethyl acetate soluble fraction of P. parviflorum. Both compounds (at 5, 10 and 15 mg/kg, i.p) were assessed for their in vivo sedative and muscle relaxant activity in open field and inclined plane test, respectively. The geometries of both compounds were optimized with density functional theory. The molecular docking of both compounds were performed with receptor gamma aminobutyric acid. Both compounds showed marked activity in a dose dependent manner. The docking studies showed that both compounds interact strongly with important residues in receptor gamma aminobutyric acid. The reported data demonstrate that both compounds exhibited significant sedative and muscle relaxant-like effects in animal models, which opens a door for novel therapeutic applications.
